Metadata is stored in a tree-like hierarchy, so a channel's metadata might look something like the diagram on the right.Metadata means "information about information."
Awasu brings news to you via your feeds but it also tracks a lot of additional information about it all e.g. when a feed item was published, who wrote it, if it has any enclosures, etc.
This metadata can be included in templates using the {%CHANNEL-METADATA%} and {%ITEM-METADATA%} parameters.
Metadata is stored in a tree-like hierarchy, so a channel's metadata might look something like the diagram on the right.
Each piece of channel metadata is accessed using the {%CHANNEL-METADATA%} parameter, so if you were generating an HTML page, you could create a link to the author's home page like this:
<a href="mailto:{%CHANNEL-METADATA% author/url}">
{%CHANNEL-METADATA% author}
</a>
Entries in the metadata hierarchy are either metadata values (e.g. or in the example above) or metadata groups (e.g. or ).
Metadata groups have no actual value themselves but if they are used in template parameters (e.g. {%CHANNEL-METADATA% author}) then Awasu will check the child metadata values and choose the most appropriate one.
So, in the example above, Awasu will generate a mailto: link for the author's email address, using the author's name, email address or URL (in that order of preference) as the display text.
